Help me with college decisions

Hello! I don’t really know if this is the right place to ask this, but I feel like I need to at least get some advice from people who are already in or is applying to college. I’m a Californian high school student, who got all their college decisions already. By the way, I’m staying in-state because it’s cheaper, in case someone asks about out-of-state universities. There are two universities that I got accepted to that I’m on the fence about. I got accepted into UC Riverside for my intended major Molecular and Cellular Biology (MCB). For UC San Diego, I got waitlisted and opted in for my intended major (MCB), my alt major (Bio Engineering), and a different major (political science). I intend for my undergraduate to double major in both MCB and Poli Sci, so that’s why I’m at a crossroads. Should I wait for my UCSD waitlist results or do I just jump the gun and accept UC Riverside? Thank you!
